Problem

Skills located in ~/.claude/skills/ were not being detected on Windows.

Root Cause

The YAML frontmatter parser regex only supported LF (\n) line endings:

const frontmatterRegex = /^---\n([\s\S]*?)\n---/;

On Windows, SKILL.md files may use CRLF (\r\n) line endings, causing the regex to fail and return null, which resulted in skills being silently skipped.

Solution

Updated the regex to support both LF and CRLF line endings:

const frontmatterRegex = /^---\r?\n([\s\S]*?)\r?\n---/;

Testing

• Verified on Windows: Skills now detected correctly
• Verified on Mac: No regression, skills still work

Impact

• Fixes skill detection for all scopes (user, project, plugin) on Windows
• No breaking changes

Closes #361
